Charginos Hiding In Plain Sight

Abstract

Recent 7 TeV 5/fb measurements by ATLAS and CMS have measured both overall and differential WW cross sections that differ from NLO SM predictions. While these measurements aren't statistically significant enough to rule out the SM, we demonstrate that the data from both experiments can be better fit with the inclusion of electroweak gauginos with masses of O(100) GeV. We show that these new states are consistent with other experimental searches/measurements and can have ramifications for Higgs phenomenology. Additionally, we show how the first measurements of the WW cross section at 8 TeV by CMS strengthen our conclusions.
